In other words make getting too overly drunk the equivalent of wearing stonewashed jeans and having a Donny & Marie poster hanging in your dorm room.

But like valkyrie said, you can't expect this to only work for good and not for evil. Maybe the same "peers" who convince your daughter that it's bad to get too drunk will also convince her that it's cool to throw up after every meal or shun those who are a different religion.
